By properly selecting the distances to each surface, we can extend the in-
room bass response of the speaker much deeper than its anechoic response.
Please see Figure 8.5. This is because the bass reinforcement provides a boost
which is complementary to the bass roll-off that would be present in an
anechoic chamber.
Figure 8.4 - Same conditions as above, except speaker is 6.6 feet
from the reflecting surface. Note how the reinforcement now
occurs at a lower frequency.
Figure 8.5 - Anechoic response, and in-room response with the
speaker placed 4.6 feet from the rear wall, and 3.0 feet from the side
wall. Note how the bass response is extended by the room
reinforcement.
